This research was conducted towards an MA in Byzantine Archaeology and Text (2004) at the Institute of Byzantine Studies in Queen’s University Belfast. It is published with the aim of presenting this evidence to a wider audience, and to inform future research by others in this field of study. The archaeological and historical evidence presented and analysed is surprisingly diverse and relatively plentiful, and, arguably, also compelling. Is there any evidence for contacts between the Eastern Roman or Byzantine empire and Ireland, and, if so, what form does that evidence take? This book does much to inform that debate.
